Abstract
‘Food and drinks’ is a thematic content known not to produce differential performance to abstract content on the Wason selection task. To examine the effects of context on problem responses, this content was set in a ‘diet’ context, predicted to produce differential performance, and this context was compared both with the ‘food and drinks’ presentation previously used and with abstract content. Additionally, both conditional and universal rules were used, producing six cells to the design, 12 subjects being tested in each cell. Results revealed a significant difference between the rules (in the form a rule by content interaction), content having a significant effect only when the conditional rules were used. For these rules, subjects made significantly more correct solutions in the diet condition than in the abstract condition, whereas there was no evidence of differential performance between the (other) thematic and the abstract condition. Although it is admitted that no satisfactory explanation of the rule differences seems apparent, the effect of context observed is encouraging for this line of research. It is concluded that, as subjects are shown to be capable of coding the general idea of a counter-example into relevant specific selections, they are quite capable of solving the task, but that they fail to do so unless the solution is cued by, and its outcome would be consistent with, their pre-existing belief structures.
